For context, I’m using the genai client. Trying to test file input + thinking + structured output. Got it working with AI Studio but can’t get Vertex to work (specifically thinking budget). Pannaga_J June 2, 2026, 6:01pm 2 Hi @devdutt10 I apologize for the delayed response on this issue. I know it’s been a while since you posted , are you still experiencing this issue? If you are, could you share a snippet showing how you are initializing the client and structuring your GenerateContentConfig for the Vertex call? And also Gemma 4’s internal thinking is controlled explicitly by setting the thinking_level parameter to "high" inside the ThinkingConfig object. Thanks
